Four people were shot, one killed, at a T.I. concert in New York’s Irving Plaza Wednesday night (May 25). Police said gunfire broke out at around 10:15 p.m. in a VIP room back stage, according to the NY Daily News.

Hip hop artists Maino and Uncle Murda were performing when gun shots sent people running and ducking for cover. According to witnesses, the fight started because of a beef between two rival crews associated with Maino and rapper Troy Ave. The gunman and the victims were all credentialed guests with access to the VIP area.

The NYPD said a 34-year-old man was shot in the chest and a 33-year-old man was shot in the stomach and a 26-year-old woman suffered a gunshot wound to the leg. They were taken to Beth Israel Hospital, where the 33-year-old was pronounced dead. His identity has yet to be released.
